IMPROVEMENT IN VENTILATING DECANTING APPARATUS FQR OIL-CANPS.

Specifica-tion forming part of Letters Patent No. 117,984, dated August15, 1871.

To all whom t may concern:

-Be it known that I, WILLIAM CLEVELAND, of Orange, in the county ofEssex and Stat-e of New Jersey, have invented a new and Improved Self-Ventilating Can, of which the following is a specification:

My invention is designed to obviate the disturbance and spilling ofliquids, which occurs when they are discharged from air-tight cans andother air-tight vessels which have only a single orice for the dischargeof the liquid and for the entrance of the air necessary to cause it toiiow, occasioned by the entrance of the air and discharge of the liquidthrough the same aperture. This I eii'ect in a more convenient andsubstantial way than has hitherto been done, by a ventilating-tube forthe admission of air to the upper surface of the liquid in the can,within the can itself, thus affording it the protection of the cover bystriking up7 a groove in said cover and soldering a strip beneath thesame so as to prevent the liquid from obtaining access to the groove.This strip may be made long enough to bend up into the discharge-tube,so that the lower side of the ventilating-tube shall be all in onepiece.

Figure lis plan ofthe top of my ilnproved can, showin g the spout forthe discharge of the liquid and the tube for admission of air. Fig. 2 isa vertical section on the line a' a', Fig. l. Fig. 3 is a verticalsection on the line y y, Fig. l.

The vessel or can may be constructed of sheet metal or any othersuitable material, and has an oriiice or spout, A, at the top, throughwhich it is filled, and by means of which the contained liquid is pouredout. A tube, B, for the admission of air to the surface of the liquidextends from a point, U, within the said spout and along it and the topof the can to a point near the op posite side, where there is anorifice, D, communicating' with the interior, or that part in which theliquid is contained.

When it is desired to empty the can this is effected by inclining it sothat the liquid will run through the spout A, while at the same time theexternal air enters the orifice C and passes through theVentilating-tube B to the surface of the liquid through the orifice D,avoiding any interfere-nce between the outgoing liquid and the enteringair, and causing an equable and uniform discharge through the spout A.

rllhis arrangement possesses the advantages of strength, neatness, andease of application in manufacture.

I do not claim constructing a can or other airtight vessel with separateorifices for the discharge of liquid and for the admission of air,having an outward opening in common, nor do I claim a tube for theadmission of air when the same is located on the outside of such vesseland extends diagonally from the body of the can to the spout ordischarge-orifice.

I claim- A can or vessel provided with a tube for the admission oi' air,formed by striking up a groove in the head or top of said vessel andeementin g thereto a strip to form the other side of said tube, whichtube projects into the nozzle of the can at the side uppermost indecanting, substantially as and for the purpose set forth.

WILLIAM CLEVELAND.
